Arthur Fils became the youngest French ATP Masters 1000 champion at the 2026 Cincinnati Open.
Fils achieved the distinction by defeating Frances Tiafoe in the men’s singles final. His 6–3, 1–6, 6–0 victory also delivered his first Masters 1000 title, the biggest championship of his career at that point.
The French achievement connects Fils with Jo-Wilfried Tsonga, the previous Frenchman to win an ATP Masters 1000 tournament before Fils’s breakthrough. Tsonga’s most recent Masters 1000 title came in Toronto in 2014.
The record concerns age and nationality within the Masters 1000 series. It does not mean Fils was the youngest player ever to win any ATP title, nor does it refer to the youngest Cincinnati champion regardless of country.
